The chief sources of information have already been given in the footnotes. Others will be found in the chapter as originally published in 1918 (see page 178). FOOTNOTES: [138] This chapter is condensed from one of two “Studies in the History of Physical Education” published for the author by the Society of Directors of Physical Education in Colleges, in 1918. [139] See page 77. An abridged translation of this book, by V. K. Hjort, curate at Holmens Kirke, was published in Copenhagen in 1799 (see page 79). [140] “Lærebog i Gymnastik for Almue- og Borger-Skolerne i Danmark. Kjøbenhavn 1828. Trykt hos Andreas Seidelin, Hof- og Universitets-Bogtrykker.” A German translation was published: “Lehrbuch der Gymnastik für Volks- und Bürgerschulen. Aus dem Dänischen übersetzt von C. Kopp, Gymnastiklehrer am Königl. Schullehrer-Seminar in Tondern, Dannebrogsmann. Mit vier Steindrücken. Tondern 1831. Gedruckt in der Königl. privilegirten Buchdruckerey der Wittwe Forchhammer.” Tondern was then a Danish town, but the German language was used in the _Seminarium_. State aid was given toward the publication of the book. [141] “Lærebog i Gymnastik til Brug for de lærde Skoler i Danmark. Ved F.
